From 415a64aa8dc6b4fc478609c549ca652d95a12f13 Mon Sep 17 00:00:00 2001 From: Huy Nguyen Date: Tue, 18 Jul 2017 16:08:46 -0500 Subject: net/mlx5: QPTS and QPDPM register firmware command support The QPTS register allows changing the priority trust state between pcp and dscp. Add support to get/set trust state from device. When the port is in pcp/dscp trust state, packet is routed by hardware to matching priority based on its pcp/dscp value respectively. The QPDPM register allow channing the dscp to priority mapping. Add support to get/set dscp to priority mapping from device. Note that to change a dscp mapping, the "e" bit of this dscp structure must be set in the QPDPM firmware command.
